General Comment:
This draft seems to me as a well defined preparation for standardization of TETRA voice signals transport via IP networks. It addresses the current challenge of the interfacing between radio systems and control centers.

Detailed Review Comments:

2.
TETRA: TErrestial Trunked RAdio
(>>have a look at the capitals)

3.
The TETRA codec is designed in such a way that on the air
   interface two of these 30ms samples are transported together (sub-
   block 1 and sub-block 2).
(>> "these" instead of "theses")

Codec payload is specified for TDM lines with 2048 kBit/s serialisation within the
   traditional circuit mode based TETRA system
(>>place "traditional circuit mode based TETRA system" at the end)

These two formats  differ mainly ...
(>> usage of "differ" instead of "defer")

5.
Note: This example shows the usage of OSTE mapping.
(>>usage of "the" instead of "of")


Kind Regards

Steffen Schmack
